Filed: 1985-09-04
Abstract: PURPOSE:To prevent the breakout of an ingot shell by moving the part, at a prescribed height, of a gate of a molten steel receiver facing the end face of the ingot in synchronization with a moving mold. CONSTITUTION:The part, at the prescribed height, of the longside gate 4 of the molten steel receiver 5 facing the end face of the ingot in parallel with the drawing direction A thereof is moved in synchronization with the moving mold 1 in the stage of continuously drawing the molten steel from the receiver 5 to a thin sheet shape by the moving mold 1 and forming the thin sheet.

Then a counter 2 commands a the high-order address of the page memory PM corresponding to the row read by the image sensors IS2 and IS4. Since a counter 3 commands a high-order address corresponding to the read position of the image sensors IS1-IS4 in the column direction, the picture information by one line of data stored in the page memory PM is stored in the ascending order and the one line of picture information is outputted from the page memory to an external device. Thus, the picture information read by the image sensor is extracted as one line of picture information with simple constitution.

Abstract: PROBLEM TO BE SOLVED: To obtain a sensing system by which the concrete failure position of a lifeline is grasped in a short time and whose restoration time is shortened by a method wherein many simple failure acquisition sensors are installed along the lifeline. SOLUTION: For example, slave stations 3 exclusively used for failure detection are installed in various places of water pipes 104 to respective households from a water purification plant 102.

Every slave station 3 detects the damage of every water pipe 104 by means of a simple water pressure sensor which obtains ON-OFF information, and it transmits, by radio, its data to every relay station 4. The data is transmitted, by wire, to a base station 5-1 from every relay station 4, and it is sent to a water supply control center 6 from the base station 5-1 by a radio communication. Since many slave stations 3 are arranged, the damaged point of every water pipe 104 can be specified immediately on the basis of the data. A data and failure-detection base station 12 is installed at the base station 5-1.  The salve station 12 has a function to detect data on a water pressure, a flow rate or the like in addition to the function of every slave station 3.
